Abstract
An injector for a material transport system includes a helical inducer having a housing with a fluid input port, a material input port and a discharge port, each port is open to an internal chamber of the housing. A rotor with a helical blade is mounted to the housing and constrained for rotation within the chamber. A fluid entering the fluid input port is formed into a fluid vortex having a ventilated core by the rotating rotor blade. A feeder assembly feeds the material to be transported into the material input port where it is carried by the fluid vortex to the discharge port for transmission to a hydraulic transport line.
